For the historic walk only. Zipline, climb, and take a historic walk at "(Ottawa) area's most magnificent waterfalls and canyon**"
I'd sort of rate the historic walk a 2 or 2.5 but the aerial park looks good (did not try it this time) and is a nice backdrop to the historic walk so bump up to a 3.
Two parts to this attraction: (1) the aerial park and (2) the historic walk. I went here with my dad to do the historic walk and check out the aerial park to see whether I'd want to come back.
The aerial park looked cool and I would come back to try it. Ziplines, rock climbing, children's area and more! (I think)
The historic walk - I would only come out from Ottawa (eg. 1.5 hour drive) it if you brought a picnic lunch on a nice day and you sort of made the day out of it.
The walk takes 40 minutes going fairly slowly and there is a video of about 25 minutes at the end. One complaint about the walk is that you will get to a lookout point and there will be an old picture but its not clear whether the vantage point of where the picture was taken is the same as where you are looking from... annoying! The video at the end about the lives of the loggers would actually be better to view at the beginning so you can get a feel of the significance of what you are about to see. The explanations on the signs along the way are ok but would have appreciated a guide or more information.
Prices are reasonable. Website is well organized and full of information.
